工業鹽除了消費和出廠控制量的指標不一樣以外，工業鹽廠家對工業鹽消費和包裝都沒有特別的要求，外觀呈白色晶體或者是呈現微黃色、青白色，也有可能鹽內存在肉眼能夠看見的異物。
工業鹽廠家在(zai)生(sheng)產食(shi)用(yong)鹽時(shi)，從(cong)原(yuan)資料的搜(sou)集、保送(song)以(yi)及(ji)消費過程、包裝等環節都有(you)特(te)別的衛生(sheng)請求，出廠前都要承受嚴厲的檢驗，各項指標需(xu)契合(he)國度《食(shi)用(yong)鹽規范(fan)(fan)》和《食(shi)用(yong)鹽衛生(sheng)規范(fan)(fan)》。從(cong)外(wai)觀上來鑒(jian)別的話，質地白，呈細沙狀、無異味，沒有(you)肉(rou)眼能夠(gou)看見的雜物(wu)等。
